Pressure transmitter Failure Analysis and Troubleshooting]: First, the pressure transmitter no output signal This situation may occur for two reasons, first of all, to check whether the pressure transmitter power supply, and then one is connected to the wrong line. This time to do is to give the pressure transmitter in accordance with the correct wiring diagram wiring, and check to ensure that the power supply. Second, in the pressure constant output irregular jumps Caused by this manifestation first of all to check whether the pressure transmitter is grounded, whether the use of shielded cable, and finally to confirm whether the site has a strong radio frequency interference. We have to do is to use shielded cable and shielding layer grounded, and pressure transmitter and earth reliable connection. Third, the pressure transmitter is not connected to the pressure, the corresponding output value is not correct Pressure transmitter is not working in its required environment may be the cause of this phenomenon. The pressure transmitter will be moved to the required environment or take measures to make the environment meet the requirements is a reliable solution. Fourth, the pressure transmitter output does not match the measured pressure Produce this problem may be the supply voltage is not correct or external load is too large. It is necessary to check the field pressure transmitter in line with the power supply range, or adjust the external load. During the service life of the pressure transmitter, zero and full scale drift may occur. If the above phenomena occur after a long period of use, it is recommended to send the pressure transmitter back to the manufacturer for calibration to ensure high accuracy.
